6 Claims.

This invention relates to dish washing machines, it more particularly relating to means for supporting the dishes or other utensils in the machine; this application being a division of my application Serial No. 540,102, flied May 26th 193l-Patent No. 1,960,816, May 29, 1934.

The object of the invention is to provide an improved rack for holding the dishes or other utensils during the washing operation.

Another object of the invention is to provide a rack for supporting the utensils which can be readily combined with a pan having means for straining the water before recirculation over the dishes.

In the accompanying drawings:

Fig. 1 is a fragmentary view partly in side elevation and partly in vertical section showing the improved dish supporting means.

Fig. 2 is a horizontal section on a reduced scale, the section being taken on the line 2-2 of Fig. 1.

In the drawings I represents a tub or bowl, preferably formed of metal, which is stationarily mounted upon a suitable support consisting of a standard 2 having its upper end formed with an integral disk 3 and its lower end fastened to a hollow base 4 which is supported from the floor by legs 5 and has a lower cover 5 to form a housing. The disk 3 has an annular depressed portion at its outer edge to receive the bottom proper of the tub, which is formed with a central opening with the walls of the opening abutting the shoulder formed by the depressed portion of the disk, and secured to the upper surface of the disk is an auxiliary bottom member or cover 3 which overlaps and is clamped tightly to the bottom of the bowl to form a water-tight joint.

J ournalled in suitable bearings at the upper and lower ends of the standard 2 is a spindle l, the lower reduced end of which extends into the housing and has fast thereto a large pulley 8 which derives motion from the shaft 9 of an electric motor l through the medium of a small pulley ll, fast to the motor shaft, and the belt 12; the motor being supported by a bracket l3 secured to the housing 4.

Fast to the upper end of the spindle l is a horizontal cross bar l4 having each of its ends upturned to form an impeller blade l which revolves in close proximity to the wall of the tub; the lower corners of the tub being roundedas indicated at I and the impeller blades being correspondingly formed adjacent thereto.

Arranged about the inner wall of the tub immediately above the upper ends of the impeller blades are baflle members It, these baflie mem bers being of angle form with one wing of each secured to the wall of the tub in any suitable manner and the other wing thereof projecting inwardly from the well. These baflle members are in parallel relation but are each arranged at an 5 angle so that they lean from bottom to top in the direction of the travel of the impeller blades. The lower end of each baflle member has an inturned lug l7 and hung on these lugs is a pan l8, the upper edge of the pan having an outturned flange for that purpose. The pan has a' removable bottom l9 which is provided with a central opening having an inturned flange upon which is removably seated a screen member 2|. This pan member has two functions, one 5 being to provide for straining the dirty water and the other being to coact with the wall of the tub to provide a converged throat within which the v impeller blades rotate so that all of the water will be brought into intimate association with the 20 blades, the pan being rounded as indicated at I8 for that purpose. It also acts as a support for the rack now to be described.

Removably mounted upon the pan is a dish rack formed of a ring 22 which supports a number of wires so bent as to form supports for the dishes. Each wire is wrapped with a single turn at two points 23 about the ring 22 so as to provide an upwardly and inwardly projecting loop 24 and to also provide two downwardly and inwardly projecting flexible rods 25, the lower end of each of which is bent in the form of a ring 26. The rings 26 are spaced apart so that flat dishes may be inserted therebetween, while the loops 24 provide; supports upon which are laid such dishes as cups and the like, and over which are inserted such dishes as drinking glasses and the like. Within the lower portions of the dish supporting members 25 is placed a ring 21, which is supported by the removable bottom IQ of the pan and which is surrounded by a garter spring 28, this ring and spring being for the purpose of keeping the dishes which are placed between the rings 26 in place therein, the edge of a dish entering between the coils of the garter spring for this purpose.

The upper end of the bowl or tub is closed by members which are carried by a table. The table has a top which is formed by outer wooden frame members 29 to which is secured a top proper 30 of any suitable material, the table top being connected to and supported by suitable legs 3 I, one only of which is shown in Fig. 1, while two are shown in Fig. 2. ,The portion 30 of the top is provided with a circular opening 32 which is designed to be closed by a transparent cover 33, this cover being slidably mounted in suitable ways 3t on the under side of the top 38 and provided with a suitable knob or handle 35 by which it can be conveniently slid to difierent positions. Carried by the under side of the top 30 in line with the opening therein is a metal cover 36, the lower edge of this cover having a slip connection with the upper portion of the tub I as shown in Fig. 1; the upper edge of the tub I being formed with an enlarged portion I" to form a shoulder which receives the lower edge of the cover 36 which is preferably rolled to form a head as shown.

In operation, when it is desired to use the machine, the glass lid 33 is slid back and the rack filled with dishes in the manner described, and a small amount of suitable cleansing agent placed in the machine. The lid is then closed and the motor started to revolve the water irnpelling blades l5. Through means (not shown) the tub is now supplied with a suitable amount of hot water. As the water rises in the tub it is thrown upwardly by the impellers so that by watching the water through the glass lid the sumciency of water can be determined.

The action of the water is as follows: The water after entering the tub is directed to the converged annular throat within which the impellers move, this throat being formed bythe wall of the tub and the wall of the pan l8. The water is thrown by the impeller upwardly and forwardly, the water striking against the baiiies [6. Some of the water is directed inwardly by the baflies, while some of the water continues up the walls of the tub, or rather the walls of the cover 36 thereof, where it is directed inwardly and downwardly by the rounded corners thereof. Thus, all of the water is directed or dashed forcibly in all directions against the dishes in the racks, thoroughly cleansing the same.

After the tub is emptied by means (not shown), if desired, another charge of hot water may be placed therein for rinsing purposes. The lid is then opened and if the water is sufliciently hot the dishes will dry in a few minutes.

The machine is self cleansing, the water action being so violent that all parts within the machine are kept clean, but if desired the dish rack and pan may be readily removed by lifting the table sufllciently to disengage the slip connection between the tub and its cover 36 and then moving the table to one side, after which the removable part may be readily taken out. The dish rack,

pan and the bottom I9 for the pan, ring 21 and its garter spring 28, drain 2i and bowl 55 are all readily separable so that they can be each individually thoroughly cleansed at any time desired. Having thus described my invention, I claim:
